`.Format` will format date values defined in your front matter and can be used as a property on the following [page variables][pagevars]:
|
|
|
|
* `.PublishDate`
|
|
* `.Date`
|
|
* `.Lastmod`
|
|
|
|
Assuming a key-value of `date: 2017-03-03` in a content file's front matter, your can run the date through `.Format` followed by a layout string for your desired output at build time:
|
|
|
|
```go-html-template
|
|
{{ .PublishDate.Format "January 2, 2006" }} => March 3, 2017
|
|
```
|
|
|
|
For formatting *any* string representations of dates defined in your front matter, see the [`dateFormat` function][dateFormat], which will still leverage the Go layout string explained below but uses a slightly different syntax.
|
|
|
|
## Go's layout string
|
|
|
|
Hugo templates [format your dates][time] via layout strings that point to a specific reference time:
|
|
|
|
```
|
|
Mon Jan 2 15:04:05 MST 2006
|
|
```
|
|
|
|
While this may seem arbitrary, the numerical value of `MST` is `07`, thus making the layout string a sequence of numbers.
|
|
|
|
Here is a visual explanation [taken directly from the Go docs][gdex]:
|
|
|
|
```
|
|
Jan 2 15:04:05 2006 MST
|
|
=> 1 2 3 4 5 6 -7
|
|
```
|
|
|
|
### Hugo date and time templating reference
|
|
|
|
The following examples show the layout string followed by the rendered output.
|
|
|
|
The examples were rendered and tested in [CST] and all point to the same field in a content file's front matter:
|
|
|
|
```
|
|
date: 2017-03-03T14:15:59-06:00
|
|
```
|
|
|
|
`.Date` (i.e. called via [page variable][pagevars])
|
|
: **Returns**: `2017-03-03 14:15:59 -0600 CST`
|
|
|
|
`"Monday, January 2, 2006"`
|
|
: **Returns**: `Friday, March 3, 2017`
|
|
|
|
`"Mon Jan 2 2006"`
|
|
: **Returns**: `Fri Mar 3 2017`
|
|
|
|
`"January 2006"`
|
|
: **Returns**: `March 2017`
|
|
|
|
`"2006-01-02"`
|
|
: **Returns**: `2017-03-03`
|
|
|
|
`"Monday"`
|
|
: **Returns**: `Friday`
|
|
|
|
`"02 Jan 06 15:04 MST"` (RFC822)
|
|
: **Returns**: `03 Mar 17 14:15 CST`
|
|
|
|
`"02 Jan 06 15:04 -0700"` (RFC822Z)
|
|
: **Returns**: `03 Mar 17 14:15 -0600`
|
|
|
|
`"Mon, 02 Jan 2006 15:04:05 MST"` (RFC1123)
|
|
: **Returns**: `Fri, 03 Mar 2017 14:15:59 CST`
|
|
|
|
`"Mon, 02 Jan 2006 15:04:05 -0700"` (RFC1123Z)
|
|
: **Returns**: `Fri, 03 Mar 2017 14:15:59 -0600`
|
|
|
|
More examples can be found in Go's [documentation for the time package][timeconst].

|
### Cardinal s
|
|
|
|
Spelled-out cardinal numbers (e.g. "one", "two", and "three") are not currently supported.
|
|
|
|
Use the [`humanize`](/functions/humanize) function to render the day of the month as an ordinal number:
|
|
|
|
```go-html-template
|
|
{{ humanize .Date.Day }} of {{ .Date.Format "January 2006" }}
|
|
```
|
|
|
|
This will output:
|
|
|
|
```
|
|
5th of March 2017
|
|
```
|
|
|
|
|
|
### Use `.Local` and `.UTC`
|
|
|
|
In conjunction with the [`dateFormat` function][dateFormat], you can also convert your dates to `UTC` or to local timezones:
|
|
|
|
`{{ dateFormat "02 Jan 06 15:04 MST" .Date.UTC }}`
|
|
: **Returns**: `03 Mar 17 20:15 UTC`
|
|
|
|
`{{ dateFormat "02 Jan 06 15:04 MST" .Date.Local }}`
|
|
: **Returns**: `03 Mar 17 14:15 CST`
